K33 Research has proposed a 'long Solana (SOL), short Litecoin (LTC)' trading strategy in anticipation of the U.S. Securities and Exchange Commission (SEC) potentially approving altcoin ETFs. The firm highlights that Grayscale's Solana Trust, which holds only 0.1% of the SOL supply, has consistently traded at or above its net asset value, reducing conversion risk. Conversely, Grayscale's Litecoin Trust, holding 2.65% of the LTC supply, often trades at a discount, which could lead to outflows if converted to an ETF. The SEC is expected to make a decision on the ETF applications in early October. At the time of the report, Solana was trading at approximately $210, down 2%, while Litecoin was priced around $107, up 0.1%.
